Richard III 'drank a bottle a day'
"Richard’s diet when he was king was far richer than that of other equivalent high status individuals in the late medieval period."
The paper said analysis of the king’s bones and teeth showed his drinking habits changed significantly around the time he became king in 1483.
A Channel 4 documentary on the new research has also used a body double to prove Richard’s curved spine would not have stopped him fighting in battle.
Dominic Smee, a 27-year-old teacher from Tamworth in Staffordshire whose spine has a 75 degree curve like Richard’s, demonstrated that his stature would not have prevented him using weapons including medieval swords, lances, halberds and axes.
In the programme, he showed he was capable of wearing armour and riding a warhorse.
The medieval saddle, with its rigid construction and stiff back support, would have helped Richard to remain upright on horseback.
The research also suggested the king had moved out of eastern England by the age of seven, and lived further west - possibly in the Welsh Marches.
A re-interment service for the king will take place at Leicester Cathedral on 26 March next year following a week of events in Leicestershire.
Richard III, who reigned from 1483, was killed at the Battle of Bosworth in August 1485, but his grave was lost when the surrounding church was demolished.
